CSR touts power gains in ULP Bluetooth

23 Apr 2008

UK's CSR said it has conducted the first public demonstration of its Ultra Low Power (ULP) Bluetooth silicon, which consumes ten times less power than a standard Bluetooth connection.

CSR conducted its demonstration at a medical conference in Luxembourg. The Bluetooth Special Interest Group (SIG) was present in the said conference, according to the company.

The demonstration consisted of two integrated circuits (ICs) transferring ULP Bluetooth data packets 50-times faster than standard Bluetooth, meaning the devices were consuming as little as 1/50th of the power.

In establishing the connection, the ULP devices used 1/10th the power required by standard Bluetooth.

CSR's demonstration ICs employed both standard Bluetooth (v.2.1) and ULP Bluetooth radios. CSR calls these devices "Ëœdual-mode' because they support both flavours of Bluetooth radio.

ULP Bluetooth, previously called Wibree, is a complementary Bluetooth technology that can be used to transfer simple data sets between compact devices and can run for up to ten years on one button cell battery.
